Preparation of chromic acid from chromium trioxide?
A general rule of thumb in chemistry is that metal oxides in water will form acids: CrO3+H2O -> H2CrO4. In fact, Chromium Trioxide is often sold as Chromic anhydride, that is, the anhydride of Chromic acid (take away water from Chromic acid, and you have...)

How chromic acid is prepared from potassium dichromate and sulphuric acid?
Chromic acid is the acid in chromic acid. The chemical formula is H2CrO3 (Not correct)Added & Corrected:Often the species are assigned the formulas H2CrO4 (dihydrogen chromate) and H2Cr2O7 (dihydrogen dichromate).The anhydride of these "chromic acids" is chromium trioxide, also called chromium(VI) oxide (2CrO3=Cr2O6).Regardless of its exact formula, chromic acid features chromium in an oxidation state of +6 (or VI), the highest known.

How you will prepare chromic acid solution?
Take 20g of Potassium Dichromate powder and make a paste using small volume of water. To this add 300ml of concentrated Sulphuric acid with lot of care. Your Chromic Acid is ready. Use only Glass appartus for preparation and storage of chromic acid. Use rubber gloves while handling chromate and acid.
Why does chromic acid react with aldehydes?
Because chromic acid is an oxidizing agent.
